383 needs more power

Here is a little different approach for you for some more "Seat of the Pants" performance.

What type of wheels are you running, are they steel ? There is a comparison between the weight of the Steel Wheels and the much lighter Aluminum Wheels. The people running the 7" wide Steel Cop Car Wheels, man those are really really heavy . . . just even picking them up.

Here goes: so on average the steel wheels weigh 20 lbs more per wheel as compared to the lighter aftermarket aluminum wheels. Times 4 that is 80 lbs of rotating mass that you have to spin up every time you take off and then for braking you have to slow it back down again.

So this is like having an 80 lb flywheel that you have to spin up and slow down every time you start and stop with the steel wheels. Swapped to the aluminum wheels on one of my cars, noticeable improvement. Making better use of the power you are already making, kind of like fully releasing the emergency brakes that are slightly dragging. Lighten up the load, and it goes to beat heck, better gas mileage too.

Have Fun with your 383 A Body . . .
